Most products
used on an everyday basis never get a thought from a layperson about their
making. As a rule, nearly every article is made using plastics, glass, metals
and rubbers. However different the material of production may be, the process
remains the same – injection molding. Among all such materials of construction,
the most common one is plastic.

The evolution of
plastic injection molding industry

At present,
close to thirty million tons plastic are manufactured on a day-to-day basis.
The significance of plastic as a material for construction is due to its high
availability; almost 60,000 variants of this material are manufactured at
present.

However, the
prosperity of injection molding technique began with the innovation of resins
such as Styrene, K Resin and Nylon 6/6. Another factor that propelled the
growth of this molding technique was the manufacturing of ultraviolet
inhibitors and different additive colors.

In 1980s, the
plastic material was given prominence with the development of horizontal
injection molding machinery. With the beginning of high-end vertical mold
machines and hybrids molding systems, it became possible to manufacture plastic
products with unimaginable contours and tight dimensional tolerances. In the
past, the process of molding was daunting and accounted for several injuries.
However, the development of technology (such as robotic controls and
hydraulics) has helped the process become safer with each passing day.

How plastic
molding industry got better?

Notwithstanding
the wonders of plastic injection molding, the procedure drew flak from several
green revolutionists due to the material it used. However, large shares of
revenue and energy are spent to make plastic environmentally more acceptable.

With the
fruitful attempts to make plastic recycling possible, the entire process of
injection molding has become efficient. The developments of high-strength
thermosetting polymers have helped enhance the durability by leaps and bounds. Several
pet bottle moulds are made from thermosetting polymers to increase their strength and
capacity to withstand high temperature.

Apart from
injection molding, one of the most common techniques used for manufacturing
hollowed plastic products is blow moulding. Presently,
innovative plastics are introduced to make possible impeccable precision and
close-tolerances in the final product.

Nowadays, the
consumers’ convenience is placed at the highest priority by players belonging
to several industries, especially the plastic bottling sector. The plastic bottle
manufacturers are leaving no stone unturned to give consumers bottles that are aesthetically
pleasing and easy to handle.

In earlier days,
the plastic bottle producers had a tough time in shaping the bottles,
especially those having complex contours. Even after hard work and dedication,
the results were not satisfactory. Such growing frustration urged several
plastic bottle producers to take help of technology. After research, a
technology finally came up that assisted plastic bottle manufacturers in reducing
their everyday manufacturing distresses; the technology came to be known as
blow molding.

What is blow
molding all about?

The most trusted
process for creating plastic containers and hollowed components is blow
molding. In blow molding, the plastic is shaped by several processes such as
stretching the material, injection or extrusion.The process gets started by heating and
consequently melting the PVC, polythene, or any other plastics before beginning
the molding process. The melted plastic has to be transferred to hollowed
tubes. Compressed air is used in the hallowed tubes for giving the molten plastic
the desired shape.

The blow molding
process at a glance

Beginning the
blow molding process is no rocket science. The process begins by feeding the plastic
granules to the storage compartment. The storage container has motorized
threads meant to rotate as well as compartmentalize granules. The compartments
(having granules) are subject to extreme heat. Once the granules are melted,
they are transferred to the mold. The mold is subjected to intense air pressure,
helping the molten plastic to acquire the desired shape.
